原生JS解决方案:

 document.querySelector('input[name=gender][value=Female]').checked = true;

HTML:

<input type='radio' name='gender' value='Male'> Male
<input type='radio' name='gender' value='Female'>Female

下面是使用上述方法的示例:

<div class="ui-field-contain">
<fieldset data-role="controlgroup" data-type="horizontal">    <legend>Choose a pet:</legend>
    <input type="radio" name="radio-choice-2" id="radio-choice-1" value="choice1">
    <label for="radio-choice-1">Cat</label>

    <input type="radio" name="radio-choice-2" id="radio-choice-2" value="choice2">
    <label for="radio-choice-2">Dog</label>

    <input type="radio" name="radio-choice-2" id="radio-choice-3" value="choice3">
    <label for="radio-choice-3">Hamster</label>

    <input type="radio" name="radio-choice-2" id="radio-choice-4" value="choice4">
    <label for="radio-choice-4">Lizard</label>
  </fieldset>
</div>

在javascript中:

$("[name = 'radio-choice-2'][value='choice3']").prop('checked', true).checkboxradio('refresh');

如果您希望它是真正动态的，并选择与输入数据相对应的无线电，那么这是可行的。它使用传入数据的性别值或使用默认值。

if(data['gender'] == ''){
 $('input:radio[name="gender"][value="Male"]').prop('checked', true);
}else{
  $('input:radio[name="gender"][value="' + data['gender'] +'"]').prop('checked', true);
};

例如，你有这样的单选按钮:

    <input type='radio' name='gender' value='Male'>
    <input type='radio' name='gender' value='Female'>

你想检查一个值为“Male”的onload，如果没有检查无线电:

    $(function() {
        var $radios = $('input:radio[name=gender]');
        if($radios.is(':checked') === false) {
            $radios.filter('[value=Male]').prop('checked', true);
        }
    });

单程怎么样?

$('input:radio[name="gender"]').filter('[value="Male"]').attr('checked', true);
